Merged Modules
A merged module consists of a Master module and one or more Slave modules
connected together by a merge cable connector. Each module has its own merge
cable connectors. The local bus sends the system clock of the Master module to
the Slave modules. The merged modules must be located in adjacent slots.
The merge connector passes 48 signals between adjacent modules excluding the
system clock. These signals consist of 16 trigger event signals, two storage
control signals, 26 clock sample/control signals, and four data-login control
signals.
Memory Erasure
To clear the volatile memory from the module you must turn the power off for at
least 20 seconds. NVRAM does not contain any acquisition data; it only contains
calibration constraints.
